IRVINE (AP) — Murder charges have been filed against a driver accused of a hit-and-run crash in Orange County that killed a woman and her 2-year-old granddaughter.

The charges were filed Tuesday against 20-year-old Alec Scott Abraham of Costa Mesa. He'd earlier been charged with vehicular manslaughter. The new charges carry a possible sentence of 30 years to life.

Abraham remains jailed. It's unclear if he has an attorney.

Authorities say Abraham's Mustang sped through a red light and hit another car in Irvine on June 10.

The crash killed 54-year-old Katherine Hampton of Lake Forest and her granddaughter, 2-year-old Kaydence Hampton.

Hampton's daughter and 7-year-old grandson had broken bones. The crash also forced cars into a Honda Civic whose driver was slightly injured.

The driver fled. Abraham was arrested the next day.
